.To all whom, it 11i/ay concern:

Be it known that I, GEORGE W. SHARER, a

citizen of the United States, residing at Terre Haute, in the county ofVigo and State of Inl diana, have invented certain new and usefulImprovenients in Driers; and Idohereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to. make and use thesame.

My" invention relates, generally, to driers which can be uscd'ifordrying lumber, brick, pottery, terra-cotta, terra-cotta lumber,` andother similar substances, and particularly relates to that class inwhich terra-cotta, lterracotta castings, and terra cotta lumber andbricks are dried. p

.The object of my invention is to improve .thegeneralconstruction ofdriers of this kind;

and the invention therefore consist-s of constructions and combinations,all as will hereinafter be described and claimed, reference being had tothe accompanying drawings, in which- Figure 1 represents a perspectivewith parts broken away to show the construction; Fig. 2, a horizontalsection, the upper right-hand part being through the drying chamber,the. up per4 lefthand part through the fines, and the lower part throughthe furnaces on line :r x, Fig. 3; Fig. 3, a front elevation with partsbroken away to sh'owthe furnace and flues in section; Fig. 4, alongitudinal section through one of the furnaces and one of its finesand taken on line 4 4, Fig."2; Fig. 5, a longitudinal section on-lines 55, Fig. 2; Fig.'6, a longitudinal section on line 6 6, Fig. 2;' Fig.7,*a transverse section ofthe furnace, showing the mannerof usingpetroleum as a fuel; and Fig. V8, va longitudinalsection on line 8 8,Fig. 7.

The drying-'chambers A, which' may be of any desired number,separatedfrom each other by' partitions A', which rest upon longitudinal walls A2under the floor of the drier,'are of or.- dinary construction. Beneaththe dryingchamber are the lines a, a', and a2, formed by thelongitudinal division`- walls A2 and tine-V walls A3, the iloorA of thedrying-chambers,

and the bottom or foundation of the drien These flues open atl the rearend into a transversctlue, A, which'is connected at its ends .mainpassagec3 in the wall B leads. ter passage follows the inclination ofthe flue,

V.furnace is provided with two sets of ues separated from each other bythe hollow divisional walls, and the sets of dues are subdivided bymeans of a vlongitudinal partition, b, forniing individual or sub fillesbb2, and terminate in chamber As at apoint opposite to the iiuel c underthe drier. The object -of` this construction is to concentrate the heatof the products of combustion upon the walls containing the air-ductsand vthen disseminate it equally thetlues a, c', anda, the transversedue A5', and chimneys'Al, placed at each end' of the latter, so as tmake the tlues draw equally.

The sub-fines bvb2 open into the distributing- .under the drier by meansof the chamber A8,`

chamber B in the back partof the furnace B?, v

which is sunk partly or wholly below the surface and provided iu frontwith the workingpit 13". The space between it and the drier is alsoslightly depressed for the transfertrack for the truck to be moved from-the drier.

In the walls which divide the furnaces are formed the air-ducts O andC', separated from each4 other by the tile G2.- The ducts C, exceptthose at the ends, as shown in Fig. 2, are formed oftwo separatepassages, c c', joined together by the transverse passage c, from whichthe This lat andthe upper end terminates ina passage, C3, in the drierpartition-walls, (see Figs. 1,4, and

.5,) so that the heat will be equally distributed 'to thedrying-chambersin each side of the wall.

Thev lower flue, C', is formed of passages c* c5 c", which respectivelycorrespond to and areA formed underneath the passages c, c', and c.Passage c is connected with a transverse passage, cl, bya short passage,cs, immediately un der passage ci.; This passage is connected at eachend with the passages ci in the walls B' and opens into 'the-transversepassageCitseeFi s.

1 andlyin the drier partition-walls. Byt is construction it will be seenthat I am enabled to heat thea'ir to a higlrtemneraturc and evenlydistribute it in the drying-chambers, and also heat the bottom of thedrier evenly by means of the'producls of combustion. If desired, astca1n-pipc, D, may be placed in the drier. This construction of drierwill dry any ordinary article, such as lumber, brick, terra-cotta,terra-cotta castings, terra-,cotta lumber, and similar articles. v

In Figs. l, 2, 3, andi the furnace is shown with a grate, and in Figs. 7and 8 a device is shown whereby petroleum orhydrocarbon can hesubstituted for the fuel used in the furnace having a grate.

E in Fig. 7 represents a pan having a. noz1 rdeepening` in its bottomand connected-with a water-supplying device by means of a pipe, l',which iucloses a second pipe, E2, through which oil is supplied to thepan F. The water und oil pipes are supplied with suitable cocks toregulate thedowinto the pan. In the walls of the furnace are formedair-passages, which lead upwardly into a chamber, E3, that opens intothe fire-box. .This chamber is divided 'into compartments by bricks E,ar-

ranged at suitable intervals, so that the air ad! mitted to the [ire-boxwill be in jets.

Vhat I cla-im as new isv In a drier, the combination of thedryingehambers having fines under the bottoms, fu rnaces having;- luescommunicating with the flues bencath'the dryingchambers, the airducts Cand C' in the sidewalls of the furnaces. and air-ducts c3 und c", formedin the divisional walls of the furnace-lines and delivering` into theair-inlets of the d :ying-chambers, and the air-ducts c being; connectedwith duct (l by lateral passages, and air-duets c being connectedtogether b v the d uct ci, and by it with passage or duct C',substantially us described.

In testimony whereof l. uiix my signature iu presence of two witnesses.
